Kinetic Energy + Potential Energy Quiz Study Guide Flashcards
1
Q
Kinetic Energy
A
- The energy of an object due to its motion and position. Usually used to describe a large object.
- The larger an object is, the more kinetic energy it has.
- Ex: mass and velocity
2
Q
Mechanical energy
A
- the energy of an object due to its motion and position
- usually used to describe large objects
- It is the sum of kinetic and potential energy
3
Q
Non-mechanical energy
A
- the energy of an object that is NOT due to its motion or position
- usually used to describe an object at it’s atomic level
- Ex: Electrical energy, chemical energy, thermal energy, sound energy
4
Q
Mass
A
- The larger the mass, the more energy is needed to move an object
- The heavier the object is, the more GPE the object has
5
Q
Velocity
A
- velocity is another way to measure motion.
- velocity is the speed of an object with direction
6
Q
Potential Energy
A
- Potential energy is energy stored in an object due to the object’s position
7
Q
Gravitational Potential Energy
A
- Gravitational potential energy is due to elevated positions
- Gravitational potential energy is used at a later time to cause an object to move
- Once the person steps off a diving board, the gravitational potential energy is converted into kinetic energy and the person falls (moves)
8
Q
Gravitational Acceleration
A
- The free fall acceleration of an object in vacuum without any drag
- This is the steady gain in speed caused exclusively by the force of gravitational attraction
9
Q
Height
A
- The higher the object is off the ground, the more GPE the object has
10
Q
Gravitational Potential Energy Equation and Unit + Kinetic Energy Equation and Unit
A
- GPE = mgh
GPE = (kg)(9.8 m/s) (m) - KE = ½ mv2
(Kinetic E: (0.5) (mass) (v x v)
